VlGNETTE-BOARD.

SPECIFICATION forming part of Letters Patent No. 244,440, dated July 19, 1881.

Application filed August 19, 1880. (Model.)

To all whom it may concern Be it known that I, CHARLES W. EARLE, of Elkhart, in the county of Elkhart and in the State of Indiana, have invented certain new and useful Improvements in Vignette-Boards; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to improvements in vignette-boards for the photographic art 3 and it consists of an adjustable plate arranged to carry the vignette-plate, and which is pivoted to a plate or frame which is adapted adjustably to the ordinary printing-frame containing the negative to be vignetted, and its object is to facilitate the vignettingof the photograph, and to provide means whereby the vignetteplate can be adjusted to any desired position over the negative without disturbing the negative after once being placed in the printingframe, and bythe peculiar construction of the vignette-plate the vignetting process can proceed as well in the shade as in sunlight, which is not the case with the vignette-plates now in use. All will he more fully described hereinafter.-

ln order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its operation and construction.

Figure l represents an elevation of the apparatus complete, the adjustable plate being in an adjusted position, as indicated in dotted lines 5 Fig. 2, a central sectional view; and Fig. 3 represents the vignette-plate D full size, in order to set forththe construction more clearly.

In the drawings, A represents the ordinaryT photographic-printing frame, upon which is placed a removable plate or frame, B, and held thereon by means of the spring-links M. Said plate B is provided with the aperture S' covering the negative-plate M', over the object thereon. The edge of the aperture S should be suitably beveled on the under side, admitting the diffused light to enter well under the plate, so as to fully cover the negative.

Upon the plate or frame B is pivoted the plate C. This plateis arranged to carry the vignetteplate D, which is suitably held thereon. Be-

neath the plateD, and in the plate C, is the aperture S, having its edge beveled like the plate B. This aperture is somewhat smaller than the aperture S', but arranged as shown in relation to it. The plate O is pivoted to the plate or frame B by the thumb-nut and screw N. Said screw plays into suitable slots that are so arranged as to admit of a vertical or horizontal adjustment of the plate G, carrying the vignette-plate D over the negative during the printing thereof. The thumb-screw also serves to hold the bottom end of the plate C rigidly in position, and the top end is held by the band c, or in any suitable manner.

The plate D is the vignette-plate, preferably made of metal, having the aperture S". The edge of said aperture is suitably serrated, and the serrated points twisted to form a proper angle with the surface of the plate. They are light-deiiectors, for diffusing the rays of light.

The advantages embodied in this style of vignette-plates are as follows:

f First, the pla-tes, being made of metal, are more durable.

Second, the vignetting can be produced as perfectly in the shade as under the direct rays of sunlight, which is not the case when employing the ordinary style.

Third, The How of light can be controlled by changing the angle of the serrated points.

ln the ordinary method of producing the vignette-photographs the light does not diffuse evenly and softly. These objections are entirely overcome by the use of my invention, consisting of the adjustable plate carrying the vignette-plate and the peculiar construct-ion of the vignette-plate.

Having fully described my invention, what l claim, and desire to secure by Letters Patent, is

l. In a printing and vignetting frame, the combination of the frame A, having the plate B, the adjustable plate C, set-screwN, working in suitable slots in the plate B, the plate D, the aperture S, the serrated edge of the same, with the serrated points twisted to a suitable angle to the surface of the plate, for the purpose of diffusing the light, substantially as described and shown.

2. In a printing and vignetting frame, the plate D, provided with the aperture S formed IOO therein, and the edge of such aperture having a suitable number of light-deectors formed by serrating the same and then twisting the serrated points to a proper angle to the surface of the plate for the purpose of diffusing the light, substantially as and for the purpose specified.

3. A Vignette-plate,D,made of metal and having the aperture S", the edge of such aperture 1o formed into a series of light-deectors by being out and then twisted to form an angle with the surface ofthe plate, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 23d (lay of 15 July, 1880.
